Some people think of the saying âopposites attractâ, meaning that essentially they are very different but they are attracted to one anotherâs differences. Opposite signs in astrology are really quite different from either of these ideas. Opposite signs are really like two side of the same coin, they essentially ARE very similar, and are concerned with similar things but they are just oriented towards the SAME thing from an OPPOSITE direction. For example, the opposite signs of Leo and Aquarius. Both signs are concerned with creativity, with innovation, with progress and expression, with inventiveness. However, the Leo approaches these concerns from a PERSONAL standpoint. They care about personal self-expression, creativity and progress, etc.
